' Be it known that I, 'EaNEsrREnA-Un, of

theeity of Mpntreal, 'Province of Quebec, Dominion of ,Canada, and being a subject ofthe King of England, have invented certain new and useful Improvements inTrain-Oontrolling Means, of which the following is. a

full, clear, and exact description, such as will enable others skilled in the artto which it apertains to-makeand use the same, reference ei .had to the accompanying drawings dli illustrate the preferred form of the in:

vention, tho h it is to be understood that the invention 18 not limited to the exact de-- tails ofjconstruction shown and described, asitis obvious that various modifications thereof willbccur to persons skilled inthe. art.

. means adapted for use in stopping trains and contemplates an automatic system of control- 1 This invention relates tov new and useful which is entirely independent of theaction of the engine .driver in the event of his tram passing into a track zone whichis occupied y another train and the object ,ofthe invention is to provide automatic eIectr'omecl1anically operated means for stopping trains under circumstances as specified.

In the drawings similar characters of refe ence'denote corresponding parts .in all the views in which: k Y Figuresl and 1' illustrate, diagrammatically, a system of electrical track connections adapted to cooperate with the mechanism carried by the train, and preferably by the engine, 'for the purpose of establishing lines of electrical communication from said track system toelectro -,mechanicallyoperable means on said engine. electrical diagram, which is illustrated in connection with a single line of'track, it is to be' observed that onl one track zone is shown for convenience o illustration, and to avoid a multiplicity of drawings, but it will be readily understood that by suitable connecting lines, Within the 'skillof an electrical engineer, amplifications of said system-ma be arranged to.ada t it to a series of trac zones or to a doub e track system as well. Fig. 2 shows alocomotive and tender whic is equipped with the invention, illustrating a the relative location of cooperating parts.

15 illustratesin detail means, emplo ed for making'and breaking circuit hereina ter explaine Refe cylinder a apted to contain'compressed air, to be supplied from any suitable source, and, connecte with this cylinder is a conduit-6 to the mechanical-parts a which leads to achamber 7 which chamber is tapped by three tubes numbered respectively 8, Q'and 10. I

In convenient proximity to the chamber 7 is a valve 11 having a stem 12 which is connected by the lever 13 'and link 14 with the rod 15 whichrod is positioned in the lower portion of the case 16 and adapted to reciprocate therein as hereinafter described. Se-

cured on this'rod 15 is a nut or, 00119.! 17

against which rests a block 18 held on a noncircular portion of said rod, or keyed thereto, to prevent rotation of said block independent of the rod. Secured to the bottom of the case 16 is an angle 19 between which angle arid said block 18 is held an expansion spring 20 normally under compression.

Carried in the guides 21, in which the rod 15 is held, is a second rod 22 with which is connected a torsion spring 23 at one end while. the opposite en of said sprin' -is connected with one.of the locks 21. -'I e tendency of this spring 23 is to rotate the rod so 110' p1 es, and-effectually stopping the train.

. 11 case a train-is automatically stopped. .asherein' described it will be impossible for maintained by t le to throw-the said lever manually-against thepressure in c linder 57-, it will be impossii by the torsional spring 23,into the horizontal position shown 1n. dotted lines in Fig. 11 40 throug end of said-pin is in contact with the hanger .raise' the rockable lever-24, but the'magnet 27, being energized, ,will hold its slotted or conduit 68ileading to the-emergency brake the engine driver to throw the throttle lever into position to again start the train until the. circuit to' pilot magnet is broken by pushing up on the rod and opening the air-cock 76 to permit exhaust of pressure to atmosphere, "owing to the fact that the forward positions of the pistons referred to will be e pressure behind them. For example, until this pressure ceases, if the throttle lever 56 ismoved outwardly against the pressure in cylinder .57 the locking pawl 55, carried by said throttle lever Wlll not engage --with-the' notches in its cooperating rack or segment 48 owing to the fact that sai pawl. will "remain retracted under pressure ofthe; air incylinder 51 and, if it were possible to-lock sai v throttle lever to hold the throttle valve open, consequently, as soon as said throttle lever is released it will immediately-fly back to position to shut off steam cam face of .block 18 will rock the cam 35 to armature 28 in such close relation to the core of said magnet thatthe end of the short pin 38 will-not enter the slot 39 in said armature and, as soon as pressure is'removed from the lever 33, the member 24 will be forced whereupon the stress of the spring 20 will again open the valve 11 as before described.

If the engine driver 'should attempt to denergize the magnet 27 by breaking clrcuit the mercury cup 46, by pres'sin upwardly the-push 'pin 75, the circuit 32 wil only ren-ain broken while he holds said push pin in an elevated positionand the upper 42 beeafise as soon as he releases said push pin its spring 49-will force the pin downwardly, thereby permitting the pin 44 to drop and again close circuit'through said mercury cu as before described. Thus it will-be evident that it will be practically. impossible to start a train equipped with the present invention when once it has been automatically stopped, while it. is on the insulated rail section from which current is supplied to the pilot magnet and, to the larger magnet 27 until circuit to said insulated rail section is broken as described in connection with the diagram shown in Fi s. 1 1*.

While the conduit 6 is shown and e'scribed as an air pressure conduit it is to be understood that said conduit may be' connected with the steam supply andsteam pressure be used instead of air pressure with equally good results.

In Fig. 15. is illustrated the detail an.

struction of one pair of magnets and associated parts which may be' used with the electrical track arrangement shown in Figs.

1-1 and while it is to be understood that any convenient means for accomplishing the ob'ect of this particular apparatus maybe su stituted therefor a brief description thereof follows: i I

The magnets 78 and 79 are supported upon asuitable base 80 and wired as shown in connection with either air of associated magnets as illustrated in th tween said magnets is'a post 81 on which is e diagram. Be-

pivotally supported a double rockable'arma ture 82, the'pivot whereofpassesthrough a bifurcated upward extension of the post/81 whileja s ring 83 is positioned so as to-normallyhoid the curved contact pin 84 carried by=said armature. outof the mercury 85. in the cup 86 and connected with the said cup is a binding post 87 which oarries' a-metal plate 88 to complete circuit-tosaid binding post and, a line connected therewith. A

second wire runs to the bindin post 89. and said latter post isin electricaf the armature 82. Thus circuit to magnet 78 will energize said ma et, draw down the pin 84 into mercury and close circuit through the line 90 while circuit to magnet '-79- will,

from said mercury. thereby destroying the circuit established through the mercury cup.

/Vhen air pressure is cut off the expansion springs 52 will automatically restore the pistons in the several cylinders 51 57 and 73,

to their normal positions. Cooperating'with said mechanism is an electrical track arrangement adapted to close the circuit 32 topilot magnet 40 and while said track arrangement may be varied, one diagram is shownherewit- 1.

Referring to the diagram shown in Figs. 1 1, and considerin a train moving from east to west (right to left), it will be observed that when the train reaches A the circuit X .a-a will be closed to magnet 'B thereby drawing down the left handgpolition of its armature-and (partly closing circuit through its associate mercury cup, 86 to insulated rail section -D througtfitlie line -b and magnet E, but as there is nothing to bridge the gap between the companion insulated railmembers of the section -D the magnet E is not yet energized, nor will it be until a train reaches this section When the first train ass'es over sectionC no result follows. hen, however, this train reaches section D- circuit will .be completed through the trucks of the train and the magnets E and F will circuit with with the aid of spring,83, break said circuit by i :rookingth armature to elevate said pin 84 be energized, thus closin'g circuit to the oppoisit'e rail membe'rs'of both sectiona -Ge and In the one case the'circuit will be:
